' PAPER FASTENER.

Original application filed November 16, 1906, Serial No. 6751348.Renewed December 19, 1925. Original No. 1,572,192, dated February 9,1926. Application for ressue filed March 3, 1927. Serial No.

`This invention, generally stated relates to a binder or fastener forsheets of paper, drawings, tracings, blue prints, and the like., and hasmore particular relation to a. locking arrangement therefor.

Engineers, draughtsmen, architects,' contractors and others, at presentexperience considerable difiiculty with paper fasteners forseveralre'asons, chief among which Inention may be made of the followingz-With certain types of fasteners it has been found that the weight of aplurality of sheets has the tendency to displace fastener parts whichcauses the sheets tobe insecurely held together. In other types it isnecessary to have a. device for forming apertures'to receive a pair ofspaced fastener prongs or tongues. In still other types it s necessaryto bend over a multiplicity of lugs or the like before the sheets can bedisengaged.

The leading object of the present invention is to overcome theaboverecited disadvantageous features and provide a paper fastener whichmay be attached to a series' of sheets without punching more than a,

single aperture; which when in position securely holds the sheetsinproper positon without regard to weight thereof; and which may bereadily opened to permit of removal of one or more sheets. Other andfurther objects reside in the provision of general details ofConstruction and 'arrangement and combination of parts for attaining theresults sought in said leading object. i

The invention consists of the features hereinafter described and finallyclaimed.

The nature, characteristic features and scope of the invention Will bemore fully understood 'from the following description taken in'connection with the accompanying drawings formng part hereof and inwhich:

Figure 1 is a perspective View of a paper fastener 'embodying theinvention about to be fitted into place with respect to apluralty ofsheets 'of paper or the like.

Figure 2 is a simllar View showing the fastener in secured position.

Figure 3 is a fragmentary sectional View taken upon the line 3-3 ofFigure 2, and

Figure 4 is a View of a fastener part as' stamped from a blank;

and reliable results, although it is to be unp derstood that the variousinstrumentalities of which my invention consists can be variouslyarranged 'and "organized and that my nvention is not limited to 'theprecise arrangement and organization of the instru-- mentaliti'es asherein shown and described.

Referring to the 'drawings in detail and first to'Figure 4, there isshown'a fastener part as' stamped from a blank. In practice, thinpliable metal, as brass is used. The fastener part as stamped issubstantially I- shaped with a single, central perforation 10 in thenarrow body part 11. The opposed 'ends 12-12 are of greater width thanthe body and the outer edges of each end are bent over toward each otherso as to meet at a line passing longitudinally through the center ofsaid body. There are thus provided keeper-s 13 as clearly shown inFigurel. The body portion is then bent over s'o that the two keepers'are arranged in parallelisn. It is in this form that the fastener partis sold to^ the trade, with or Without pin-clips 14, best'seen in Figure3. In 'practice a plurality of sheets of paper 15,

or other desired material, is provided With a single perforation 16through which is inserted a conventonal paper-clip M, see Figure 1. Theapertured body portion of my novel fastener part is then caused toengage over the prongs of said clip and to further engage within thekeepers 13, the prongs in practice being sufficiently long to projectentirely through the keepers. In this position the fastener part endstogether with the prongs of the paper-clip theren are flattened out uponthe uppermost sheet as clearly shown in Figs. 2 and 3. Thus the head ofthe paper-clip in one instance and the overturned or fiattened fastenerparts in the other instance serves to clamp securely therebetween saidsheets. Notonly are sheets 15 thus firmly bound in place againstaccidental displacement, but should it be necessary to remove a sheet orso it is,

keepers and lift them from the paper-clip whereupon ready access may behad to sheet or sheets desired. The paper-clips are made in various butstandard sizes and the fastener of the invention is made in sizes foruse in conjunction therewith.

It will now be apparent that I have devised a novel and usefulConstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to' givesatisfactory and reliable results, it is to 'be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A fastener for a n'aterial-binding element having projecting prongs,comprising a body portion having angular projections, and means on saidprojections for receiving the prongs of the element, said projectionsbeing adapted to be flattened with prongs.

2. A fastener for a material-binding element having projectingprongs,comprising a flexible body portion adapted to be nitially bent to formprojections, and means on said projections for engaging the prongs ofthe element, said projections being adapted to be flattened with prongs.

3. A fastener for a material-binding element having projecting prongs,comprising a substantially U-shaped body portion having means forreceiving the prongs of the element and adapted to be fiattened with theprongs.

4. `A fastener for a material-bindng element having projecting prongs,comprising a body portion having means for receiving the prongs, saidbody portion being adapted to be initially bent to receive the prongsand subsequently fiattened with the prongs.

5. A fastener for a na-terial-binding element having projecting prongs,comprising a body portion having apertures for receiving the prongs asthey project at an angle to the material to be bound, said body with theprongs being adapted to be subsequently flattened against the materialto be bound.

6. A fastener for'a material-binding element having projecting prongs,comprising a body portion having projections for cooperating with theprongs and for holding the same. said projections being adapted to 'bebent flat with the prongs.

7. A fastener for a material-binding element having projecting prongs,comprising a body portion having an aperture for the passage of theprongs of the element and projecting portions for holding the prongs,said projections being adapted to be bent to spread the prongs.

8. A fastener for a material-binding element having projecting prongs,comprsing a body portion having substantially' parallel projections andan aperture between said projections for the passage ot' the prongs ofthe element, and means on said projections for engaging the prongs ofthe element.

9. A fastener for a material-binding element comprising a body having anopening for the passage of pliable binding prongs, and having projectingkeeper portions for holding the prongs and capable of being folded flatwith the prongs.

10. A fastener for a. material-binding element comprising a body portionhaving an aperture for the passage of the binding element, and membersextending in angular spaced relation from the sides of the aperture,said members having means to receive the projecting encls of saidbinding element and adapted to be folded with said ends intojuxtaposition to the material to be bound.

11. A binding device, comprising a binding element for passage throughan opening in material to be bound, and a fastener comprising a. bodyportion having an aperture for the passage of said binding element, andportions adapted to hold the ends of the binding element and to befolded into juxtaposition with the material to be bound.

12. As an article of manufacture, a fastener for sheet bindingcomprising a body having a single opening for pliable binding tonguepenetration, and having parallel keeper portions each' of which isadapted to receive a prong of the binding tongue and capable of beingfolded to fiat, opposed position with the prongs therein.

13. A binding device comprising a paperclip having a pair of pliableprongs for passage through a single opening in sheets to be bound, afastener the body of which has a single opening for penetration of saidprongs, and parallel keeper-s for said body to receive the projectedprong ends, which keepers with the prongs therein are adapted to befolded toflat, opposed position upon the sheets being bound.

14. The method of producing a materialfastener from a. blank of flexiblematerial, which consists in forming prong receiving members on oppositesides of the blank, and bending said sides toward each other.

15. The method of producing a materialfastener from a blank of fiexiblematerial, which consists in forming apertured keepers at opposite sidesthereof, and bending said keepers into spaced' relation with each other.

16. The method of producing a material fastener from a blank' offiexible material, which consists in making an aperture in the blank,forming receiving means at opposite sides of the aperture, and bend'ngthese means toward each other.
